Where do I source the past data from?

To see previous dates data, hover above the graphs on the trend line (both the infected case as well as deaths) and you will see the data points for each date.

Sorry if this has been posted earlier. By now, everyone must be aware about the Bhilwara model ( Rajasthan ) and its commendable strategy in combating Covid-19. Isolating 6000 people in 2 days was one hell of an awesome task.

Virus could reactivate in cured patients. 51 cases have been reported in south korea. Don't know when this will end.

My understanding of Corona. I have tried to simplify it:

Corona name comes from Latin for crown. The name refers to the characteristic appearance of surface projections creating an image reminiscent of a crown.

SARS-CoV-2 is the formal, scientific name of the actual virus, a not-quite-living thing that floats around and reproduces using living cells.

COVID-19 is the name for the disease that being infected with SARS-CoV-2 causes. Coughing, fever, and immune system malfunctioning are symptoms of COVID-19.

Serious Acute Respiratory Syndrome COronaVirus 2
COrona VIrus Disease (20)19

The coronaviruses are a family of viruses of which SARS-CoV-2 is a strain. The family was classified in 1968.

In taxonomy, "strain" is the division below species. Coronavirus is not technically a species; it is a family (Coronaviridae). SARS, MERS, and COVID-19 are all in the Coronaviridae family, and also in the same genus (betacoronavirus), but after that they are separate. They are each different species within the betacoronavirus genus. There are also a coronavirus that are associated with the common cold, one being Corona Virus Strain 229E.
Coronaviruses (CoVs), within the order Nidovirales, are enveloped, single-strand, positive-sense RNA viruses with a large genome of approximately 30 kbp in length. CoV was cultured for the first time in human embryonic tracheal organ cultures by Tyrrell and Bynoe in 1965.

Among four genera of CoVs, beta-CoV includes five subgenus—embevovirus, sarbecovirus including severe acute respiratory syndrome (SARS)-CoV, merbecovirus including Middle East respiratory syndrome (MERS)-CoV, nobecovirus, and hibecovirus. Because CoVs can infect a variety of animals, SARS-CoV and MERS-CoV crossed the species barriers. Coronavirus virions are spherical with diameters of approximately 125 nm as depicted in recent studies by cryo-electron tomography and cryo-electron microscopy.

Coronavirus virus particles contain four main structural proteins. These are the spike (S), membrane (M), envelope (E), and nucleocapsid (N) proteins.
Coronaviruses contain a non-segmented, positive-sense RNA genome of ∼30 kb. The replicase gene encoding the nonstructural proteins (Nsps) occupies two-thirds of the genome, about 20 kb, as opposed to the structural and accessory proteins, which make up only about 10 kb of the viral genome. source:https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4369385/

Conspiracy by China

Caixin global, https://www.caixinglobal.com/2020-02...101521745.html, reported on the novel virus on 28th December 2019. The virus was sequenced in Chinese labs. A genomics company Vision Medicals, based in Huangpu district in Guangzhou, South China’s Guangdong province had sequenced most of the virus by 27th December, from fluid samples of a 65-year old deliveryman who was working at the seafood market where many of the first cases emerged. The patient was admitted to the Central Hospital of Wuhan on Dec. 18 with pneumonia and his condition quickly deteriorated. On Dec. 24, the doctors took fluid samples from his lungs and sent them to Vision Medicals for testing, according to Zhao Su, head of respiratory medicine at the hospital. The earliest results were returned on Dec. 27. The patient, who was transferred to Wuhan Jinyintang Hospital, later died. The company did, however, share the data with the Chinese Academy of Medical Sciences.

It showed an alarming similarity to the deadly SARS coronavirus that killed nearly 800 people in 2002-03. Samples of at least eight other patient from hospitals around Wuhan were sent to multiple Chinese genomics companies including BGI. The results all pointed to a dangerous SARS-like virus. All this happened days before China notified the World Health Organization (WHO) on Dec. 31 about the emergence of an unidentified infectious disease, 2 weeks before it shared the virus’s genome sequence with the world, and crucially, more than three weeks before Chinese authorities confirmed publicly that the virus was spreading between people.
On Dec. 30, Dr. Li Wenliang was one of several in Wuhan who sounded the first alarms and released initial evidence online. Li was punished for releasing the information and he died five weeks later, after contracting it from a patient.

Zhang Jixian, who heads the respiratory department at Hubei Xinhua Hospital, noticed on Dec. 26 that he had received a growing number of patients with symptoms of pneumonia from the neighboring seafood market. Following the reports, disease control authorities in Wuhan and Hubei on Dec. 30 issued an internal notice warning of the emergence of pneumonia patients with links to the seafood market and requiring hospitals to monitor similar cases. The notice, later leaked online, offered the first glimpse to the public of officials’ acknowledgement of the outbreak.

On Jan. 1, after several batches of genome sequence results had been returned to hospitals and submitted to health authorities, an employee of one genomics company received a phone call from an official at the Hubei Provincial Health Commission, ordering the company to stop testing samples from Wuhan related to the new disease and destroy all existing samples. Then on Jan. 3, China’s National Health Commission (NHC), the nation’s top health authority, ordered institutions not to publish any information related to the unknown disease, and ordered labs to transfer any samples they had to designated testing institutions, or to destroy them.
It was Jan. 9 when Chinese authorities finally announced that a novel coronavirus was behind Wuhan’s viral pneumonia outbreak. Even then, the transmissibility of the virus was downplayed, leaving the public unaware of the imminent danger.

Finally, on Jan. 20, Zhong Nanshan, a leading authority on respiratory health who came to national attention in his role fighting SARS, confirmed in a TV interview that the disease was spreading from person-to-person.
Two days later, Wuhan, a city of 11 million, was placed in lockdown.

The isolated SARS-CoV-2 from the oropharyngeal sample obtained from the patient with the first laboratory-confirmed SARS-CoV-2 infection in Korea. Cytopathic effects of SARS-CoV-2 in the Vero cell cultures were confluent 3 days after the first blind passage of the sample. Coronavirus was confirmed with spherical particle having a fringe reminiscent of crown on transmission electron microscopy. Phylogenetic analyses of whole genome sequences showed that it clustered with other SARS-CoV-2 reported from Wuhan.

Frequently Asked Questions

COVID-19 spread

It is carried on respiratory droplets when we talk, sneeze, and cough and these can land on surfaces or in someone’s mouth or nose and this virus is really transmissible. It can spread easily from person to person even before a person develops symptoms. 6 feet is considered as the magic distance when it comes to respiratory droplets. Being within 6 feet of someone who is sick can get you or your personal space contaminated with COVID-19.
When droplets land on surfaces, we can pick them up with our hands and transfer them to our eyes, mouth, and nose when we touch our faces. This is why hand hygiene is so important. Respiratory secretions (like snot and sputum) are also infectious so cover your coughs and sneezes.

Symptoms of the virus

It typically causes flu-like symptoms. Some patients particularly the elderly and others with other chronic health conditions develop a severe form of pneumonia.
Patients develop symptoms like fever, muscle and body aches, cough, and sore throat about 5-6 days after infection. Some people won’t get as sick, but it’s still important not to be out and about, so as not to spread the disease. A minority of patients will get worse. This usually happens after 5-7 days of illness and these patients will have more shortness of breath and worsening cough. If this happens, it’s time to contact your doctor again or even go to an emergency room. Be sure to call first so they know you are coming.

Medical Care

About 80% of people who contract this new coronavirus will feel sick, but ultimately be just fine. It’s the 20% of COVID-19 patients who get really sick. A lot of these critically ill patients wind hospitalized for pneumonia like illnesses. They typically require critical care and ventilation. Some may need to stay on ventilators for weeks at a time. Depending on how many cases develop, providing that level of care for so many people over a number of weeks runs the risk of overwhelming the nation’s health care system pretty quickly. Practising social distancing help prevent this kind of “surge” in patients.

Risk of catching

Yes. It doesn’t appear anyone is naturally immune to this particular virus and there’s no reason to believe anybody has antibodies that would normally protect them.

Concern

The challenge with COVID-19 is that we probably can’t contain it and we don’t know if we’re really prepared as a country for a massive coronavirus epidemic. If we are lucky, it will slow down a bit over the summer but the next few months look like they are going to be pretty tough for all of us. We need to be as ready as we can for whatever comes our way and know that we will get through it eventually.

Protection

Take the preventive actions you do for the cold and flu. This includes avoiding close contact with people who are sick, not touching your eyes, nose and mouth, washing your hands thoroughly and frequently and cleaning and disinfecting objects and surfaces you come in contact with regularly.
Wearing a face mask to protect yourself from getting COVID-19 or other respiratory illnesses is not recommended. Those who have COVID-19 or are showing symptoms should wear a mask to protect others from getting the virus. Any healthcare worker taking care of someone infected with COVID-19 also should wear a mask.

Antibiotic or vaccination against the virus

There is no antibiotic (they are designed for bacterial infections, not viral ones) to treat COVID-19. Scientists are already working on a vaccine, but we don’t expect to have a good vaccine until spring of 2021 at the earliest. However, ongoing trials in China suggest that there are some existing antiviral drugs that may be helpful for the sickest patients. Drugs previously in development for SARS could be effective for COVID-19.
For now, doctors can only treat the symptoms, not the virus itself.

Etymology of other diseases

Human Immunodeficiency Virus (HIV)
It originated in Congo in 1920s. Acquired Immune deficiency Syndrome (AIDS) is the name of the disease.

Tuberculosis
It originated from a group of smooth mycobacterium found in humans in East Africa.

Good news today, for the first time the number of people cured from Covid is greater than the number of new cases (in Kerala). Hope it stays that way.

This was in the news as far back as February but in Japan. I had asked about this on page 7 of this thread, but then I was not expecting any answers as this is an emerging disease and a newly discovered virus which no one knows anything much about. Experts are learning as we go

If you think we are healthy and will recover from Covid-19, please read this. We might survive, but there will be lasting health issues.

Doctor's Note: Can coronavirus cause permanent damage?

"There is evidence that COVID-19 could cause long-term lung and kidney problems. "

"It is clear that people with only mild symptoms (usually a dry cough and fever) will make a full recovery without any long-lasting damage to their bodies, but some scientists believe evidence is mounting to show that those on the moderate to severe end of the spectrum (who experience breathing difficulties and pneumonia) may be left with permanent lung damage."

"As the infection worsens, a condition known as sepsis or overwhelming infection sets in. This means that lots of organs become affected by the one infection - the kidneys being one example."

I see it's the highest single day hike in India Today with more than a 1000 new cases! Mumbai and Delhi have taken the brunt.

Edit: It has been corrected to 870. But this still is the highest single day tally I guess?

I found this to be a very scintillating read:

"Doctors Puzzle Over COVID-19 Lung Problems"

Some patients coming to the hospital have very low oxygen levels in their blood, but you wouldn’t necessarily know it from talking to them. They don’t seem starved of oxygen. They may be a little confused. But they aren’t struggling to breathe.

A whole bunch of these patients really have low oxygen, but their lungs don’t look all that bad

about 30% of COVID-19 patients who come to the hospital have more classic symptoms of acute respiratory distress syndrome, or ARDS. Their lungs are cloudy on imaging scans, and they’re stiff and inflamed, showing that they aren’t working well. The patients also have low levels of oxygen in their blood, and they are struggling to breathe.

patients with more normal-looking lungs, but low blood oxygen, may also be especially vulnerable to ventilator-associated lung injury, where pressure from the air that’s being forced into the lungs damages the thin air sacs that exchange oxygen with the blood.

doctors need to be aware of the COVID-19 patients’ symptoms and need to use the ventilator carefully and sparingly.

treating all COVID-19 patients based on the same set of instructions had a 60% death rate in its ICU.

This is a kind of disease in which you don't have to follow the protocol -- you have to follow the physiology

As with most Vox productions, well explained.

I think it was also the day when the highest number of tests were done. The ratio of positives per test was down, I think.

This is the study about antibodies in recovered patients. Some had very low antibodies compared to others but they all recovered in same time. Guess lot of things need to be studied yet for this virus.

Re-infection could happen since it happens with common cold inducing coronoviruses. So, even a vaccine could protect you only for a year or two. Or they will find a way of longer immunity.
